Acidentes do trabalho entre trabalhadores de enfermagem de um hospital universitário The occurrence of work accidents among nursing personnel at a university hospital

Foi realizado um estudo descritivo com trabalhadores de enfermagem para avaliar determinados aspectos epidemiológicos dos acidentes de trabalho acontecidos. No período de 1² de janeiro a 30 de junho de 1995 foram estudados 100 acidentes do trabalho ocorridos, o que correspondem a 8,2% de incidência acumulada no período para uma população de 1.218 trabalhadores pesquisados. Como síntese o estudo reconstroi o acidente do trabalho acontecido e os múltiplos fatores de risco presentes nas condições de trabalho de trabalhadores de enfermagem de um hospital universitário.<br>A descriptive study was conducted to assess the epidemiological aspects of the work accidents that occur among nursing personnel. The study consisted of a population of 1, 218 workers and assessed 100 accidents, that corresponded to 8.2% of all accidents that took place during the period, January 1" 1995 to June 3th 1995. The summary of this study evaluates the work accidents that occur among these nursing personnel and the risk factors presented by the working conditions of a university hospital

Paleogenomics of animal domestication

Starting with dogs, over 15,000 years ago, the domestication of animals has been central in the development of modern societies. Because of its importance for a range of disciplines – including archaeology, biology and the humanities – domestication has been studied extensively. This chapter reviews how the field of paleogenomics has revolutionised, and will continue to revolutionise, our understanding of animal domestication. We discuss how the recovery of ancient DNA from archaeological remains is allowing researchers to overcome inherent shortcomings arising from the analysis of modern DNA alone. In particular, we show how DNA, extracted from ancient substrates, has proven to be a crucial source of information to reconstruct the geographic and temporal origin of domestic species. We also discuss how ancient DNA is being used by geneticists and archaeologists to directly observe evolutionary changes linked to artificial and natural selection to generate a richer understanding of this fascinating process
